CvRTrees member oob_error is not accessible

CvRTrees has a member "oob_error" which is protected, and there is no method to access it. However, the out-of-band-error is important when you want to estimate the test set error, saving you crossvalidation when looking for parameters.

Also, the only way to make CvRTrees compute the oob error is to a) use it in the termination criteria b) calculate the variable importance. It would be nice to be able to control this independently.
